IMPROVEMENT lN COMBINED POTATO DIGGERS AND CULTIVATORS.

Specification forming part of Letters Patent No. 173,753, dated February22, 1876 application filed January 10, 1876. i

To all whom it mag concern:

Be it known that l, SAMUEL W. BARR, of Mansfield, in the county ofRichland and State of Ohio, hax e invented a new and useful farm.

implementa Combined Potato Digger and Cultivator-which machine is fullydescribed and set forth in the following specification,

reference being had tothe accompanying drawing.

- In the construction of this machine an lIOll bar, four feet long andfive-eight-hs by two frame. Arod,e,withitsendsflattened,drilled,

and turned at right angles, is bolted fast to the castings t) maketheframe substantial.

These castings are about two feet long and one-half inch thick by threeinches broad, and are formed with steps or seats, as seen at d, Fig. 2.These seats are parallel with the beam 1), and run from edge to edge ofthe eastin gs at an angle of forty-five degrees, and to the angles ofthese seats the teeth a a a are bolted fast. The blades or teeth a a aare cut from bars of steel or iron three-eighths of an inch thick by oneand a half inch broad, and are seventeen inches long, with beveled ends.These teeth, when bolted to the frame, stand less.

at an angle of forty-five degrees to it, with their sides parallel tothe beam I), and are set close enough in succession from the front andcenter of the machine to prevent potatoes from passing between them.

Ten or twelve teeth are used in a mediumsized machine, and the abovedimensions apply to the construction of a machine of medium size. Therear end of the frame is seventeen inches wide, which is deemed wideenough for ordinary potato-hills. When used to dig potatoes the machinemust be run through the center of the hill with tlie points of the teethbelow the tubers, in which case no damage will be done to them.

This machine differs from all potato-diggers that use a share or shovel,in the fact that it does not lift any dirt from below the tubers to bethrown out with them to cover more or When used as a cultivator it maybe necessary in some soils "to take out alternate teeth, in which casethe machine can be run very close to young plants, and will lloosen thesoil as deep as desired.

The teeth a, beam b, and front tooth c, in combination with the sidebeams d, the teeth being beveled at their lower ends, as shown, andsecured to the beams 01 at an. angle of about forty-five degrees, withtheir flat sides parallel with the line of draft, as shown anddescribed, and for the purpose set forth.
